*7.2. Typical Application Fields of AlCr-Based Coatings*

Applications for AlCr-based coatings cover a wide range of cutting tools and forming tools, but also components. The dominant application is for tools [67,149,184–188]. Figure 29 shows examples of tool applications. Besides the standard applications, additional application potentials must be considered as well. Examples of this are: extremely thick coatings of more than 30 μm for turbine blades [170], or multilayer coatings with an oxygen gradient for solar absorbers [164].
